Is there a tool that could be used to check the hole fill after wavesoldering. We do not have cross-sectioning capabilities here in the plant. I know that IPC calls for 50% hole fill but in our case when our quality people on the line see a partially filled hole they try and fill it with touching up. we are working on getting a grip on this with some difficulty. As a side note which parameter (% top side heater, dwell time, wave height, bottom side temp) on our Soltec wave solder oven would we want to change to possibly get greater hole fill when we have a very large heatsink part with though hole leads. I really don't have the time this time for a DOE for this and was hoping someone else has had this problem. ############################################################## TechNet Mail List provided as a free service by IPC using LISTSERV 1.8c ############################################################## To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TECHNET <your full name> To unsubscribe: SIGNOFF TECHNET ############################################################## Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information.
